The average change in temperature from 9 a.m to 9 p.m is - 0.6 °
C per hour (negative indicates temperature decreases), if the temperature at 9 a.m was 13.6 °
C and the temperature at 9 p.m was 6.4 °
C.

Explanation:

The given is,

The temperature at 9 a.m was 13.6 °
C

The temperature at 9 p.m was 6.4 °
C

The temperature at 3 a.m was 23.5 °
C

Step:1

Hours difference between 9 a.m to 9 p.m is,

= 12 hours (∵ consider a clock for this calculation)

Step:2

Temperature difference between 9 a.m to 9 p.m is,

= 6.4 - 13.6

= - 7.2 °
C

Step:3

Average change in temperature between 9 a.m to 9 p.m,


Avg = (Temperature difference)/(Time period)


= (- 7.2)/(12)

= - 0.6 °
C ( ∵ Negative indicates temperature reduction)

Result:

The average change in temperature from 9 a.m to 9 p.m is - 0.6 °
C per hour ( Negative indicates temperature reduction).
